Ideal for riders using a basic trainer, rollers, a GPS computer or a phone-based app who want simple, transferable speed and cadence data without a full smart-trainer upgrade.
The Wahoo RPM Speed and Cadence Sensor Bundle is a tidy upgrade for anyone who wants more useful ride data without replacing their head unit or trainer. Both sensors are wireless, magnet-less and lightweight, so setup is cleaner than older spoke-and-chainstay systems, and they pair with a wide range of ANT+ and Bluetooth Smart devices including many bike computers, smartphones and training apps.
In practice, this bundle makes the most sense for riders who want live cadence feedback, more complete indoor data, or a dependable speed source when GPS isn’t ideal. The cadence sensor can mount to the inside of the non-drive-side crank arm or to a shoe, which is handy if you move it between bikes or use it for studio sessions. The speed sensor mounts at the wheel hub, using wheel rotation and wheel circumference to calculate speed and distance.
For buyers here in Australia, the main thing to know is compatibility. The cadence sensor works with spin bikes when you have a suitable mounting point, but the speed sensor is not recommended for most spin bikes because it is designed for a bicycle wheel hub. If your goal is outdoor riding, rollers, a basic indoor trainer or adding sensor data to an older computer, this bundle is a neat, low-fuss option. If your smart trainer already calculates cadence well, you may not need both sensors.
Dual-sensor bundle
Gives you separate speed and cadence data so you can build a more complete training setup indoors or out.
Magnet-less design
No spoke magnet or chainstay pickup to line up, so installation is cleaner and easier on modern bikes.
ANT+ and Bluetooth Smart
Pairs with many bike computers, phones and training platforms, making it easier to slot into an existing setup.
Compact and light
At 7 g per sensor, they stay unobtrusive once fitted and are easy to swap between bikes when needed.
Flexible cadence mounting
Mount the cadence sensor on the inside of the non-drive-side crank arm or use the shoe option for spin classes and multi-bike use.
Hub-mounted speed sensor
The speed sensor sits at the wheel hub for a tidy fit and works well where GPS speed is less useful, such as indoor sessions.
Replaceable coin-cell batteries
Uses CR2032 batteries with up to 12 months of claimed life, so there’s no charging routine to remember.
Weather-resistant build
The IPX7 rating adds peace of mind for wet commutes, winter training and everyday riding.
Great for
Maybe not for
Cadence sensor mounts on the inside of the non-drive-side crank arm and should clear the frame through the full pedal stroke; for very high cadence efforts, mounting it closer to the bottom bracket helps. The speed sensor mounts around a bicycle wheel hub, not a spin-bike flywheel. These sensors work with most Bluetooth 4.0+ and/or ANT+ enabled devices, including many bike computers and smartphones.
vs Garmin Bike Speed Sensor 2 and Cadence Sensor 2 Bundle
A very direct alternative for riders wanting the same basic job done: separate speed and cadence sensors with ANT+ and Bluetooth support.
vs Magene S3+ Speed/Cadence Sensor setup
A budget-friendly option often chosen by riders building a low-cost indoor or commuter setup.
vs SIGMA DUO Magnetless Speed and Cadence sensors
Another magnet-less paired-sensor option aimed at riders adding data to compatible computers and apps.
Best value comes from the cadence sensor
For many riders, cadence is the biggest upgrade here because it gives immediate feedback for pacing, efficiency and structured intervals, especially indoors.
Check your indoor setup before buying
If your smart trainer already broadcasts reliable cadence and speed, this bundle can be redundant. It makes more sense with rollers, basic trainers or bikes used with simpler apps and computers.
Mounting position matters
The cadence sensor should sit on the inside of the non-drive-side crank arm with enough frame clearance through the full rotation. That small install detail makes a big difference to trouble-free use.
Speed sensor needs a real wheel hub
The speed sensor is designed around hub rotation and wheel circumference, so it suits actual bicycle wheels rather than most spin-bike flywheels.
